+.SH DESCRIPTION
+The QSound class provides access to the platform audio facilities.
+.PP
+Qt provides the most commonly required audio operation in GUI applications: asynchronously playing a sound file. This is most easily accomplished with a single call:
+.PP
+.nf
+.br
+ QSound::play("mysounds/bells.wav");
+.br
+.fi
+.PP
+A second API is provided in which a QSound object is created from a sound file and is played later:
+.PP
+.nf
+.br
+ QSound bells("mysounds/bells.wav");
+.br
+.br
+ bells.play();
+.br
+.fi
+.PP
+Sounds played using the second model may use more memory but play more immediately than sounds played using the first model, depending on the underlying platform audio facilities.
+.PP
+On Microsoft Windows the underlying multimedia system is used; only WAVE format sound files are supported.
+.PP
+On X11 the Network Audio System is used if available, otherwise all operations work silently. NAS supports WAVE and AU files.
+.PP
+On Macintosh, ironically, we use QT (QuickTime) for sound, this means all QuickTime formats are supported by Qt/Mac.
+.PP
+On Qt/Embedded, a built-in mixing sound server is used, which accesses \fC/dev/dsp\fR directly. Only the WAVE format is supported.
+.PP
+The availability of sound can be tested with QSound::isAvailable().
+.PP
+See also Multimedia Classes.
+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QSound::QSound ( const QString & filename, QObject * parent = 0, const char * name = 0 )"
+Constructs a QSound that can quickly play the sound in a file named \fIfilename\fR.
+.PP
+This may use more memory than the static \fCplay\fR function.
+.PP
+The \fIparent\fR and \fIname\fR arguments (default 0) are passed on to the QObject constructor.
+.SH "QSound::~QSound ()"
+Destroys the sound object. If the sound is not finished playing stop() is called on it.
+.PP
+See also stop() and isFinished().
+.SH "bool QSound::available ()\fC [static]\fR"
+Returns TRUE if sound support is available; otherwise returns FALSE.
+.SH "QString QSound::fileName () const"
+Returns the filename associated with the sound.
+.SH "bool QSound::isAvailable ()\fC [static]\fR"
+Returns TRUE if sound facilities exist on the platform; otherwise returns FALSE. An application may choose either to notify the user if sound is crucial to the application or to operate silently without bothering the user.
+.PP
+If no sound is available, all QSound operations work silently and quickly.
+.SH "bool QSound::isFinished () const"
+Returns TRUE if the sound has finished playing; otherwise returns FALSE.
+.PP
+\fBWarning:\fR On Windows this function always returns TRUE for unlooped sounds.
+.SH "int QSound::loops () const"
+Returns the number of times the sound will play.
+.SH "int QSound::loopsRemaining () const"
+Returns the number of times the sound will loop. This value decreases each time the sound loops.
+.SH "void QSound::play ( const QString & filename )\fC [static]\fR"
+Plays the sound in a file called \fIfilename\fR.
+.PP
+Example: sound/sound.cpp.
+.SH "void QSound::play ()\fC [slot]\fR"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Starts the sound playing. The function returns immediately. Depending on the platform audio facilities, other sounds may stop or may be mixed with the new sound.
+.PP
+The sound can be played again at any time, possibly mixing or replacing previous plays of the sound.
+.SH "void QSound::setLoops ( int l )"
+Sets the sound to repeat \fIl\fR times when it is played. Passing the value -1 will cause the sound to loop indefinitely.
+.PP
+See also loops().
+.SH "void QSound::stop ()\fC [slot]\fR"
+Stops the sound playing.
+.PP
+On Windows the current loop will finish if a sound is played in a loop.
+.PP
+See also play().
